Beef Pie with Potato Crust
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
In a pan, combine cold meat and chopped onions.
Add coarse sea salt and black pepper, and cook until onions are tender.
Stir in a little thickening until well combined.
Transfer the mixture to a dish and cover with warm mashed potatoes.
Place in a 400°F (200°C) oven for a few minutes until heated through.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
